Answer:
Emotions and anxiety can raise your heart rate, Body Temperature: If you become too hot or too cold your body senses a thermal stress load, The terrain, Wind, Dehydration, Diminishing glycogen stores — your muscles primary fuel source.
Explanation:
electron = negative charge (I remember this one is negative because it is not the other two )
proton = positive charge (aka "P" is for "Positive")
neutron = no charge (aka "N" is for "No charge")
Hope this helps!
Answer:
The dark colored moths were due to a genetic mutation, and were more than likely present before the Industrial Revolution. Their fitness was low because predators could easily see them on the light-colored trees. They would be eaten before they could reproduce and pass on their genetic mutation. After the trees became darkened by soot, the darker colored moths now had the survival advantage, able to "hide" from predators. The lighter colored moths became more visible to predators, and the advantage shifted. Now, the light colored moths were more visible to predators, were eaten, and didn't have the chance to reproduce. The darker moths with the mutation had the survival advantage, blending in with the soot-covered trees, and were able to reproduce at higher rates, passing the mutation on to later generations.
1. The carrier proteins via which sugar comes into pancreatic beta cells have HIGHER Km when compared to the carriers via which sugar comes into muscle cells at fasting blood sugar levels.
Explanation: A high Km amount shows a low affinity for the substrate. The carrier protein (GLUT4), which is basically observed in muscle cells, do possess a stronger affinity for glucose (low km 1.8-4.8mM) thereby making sure that maximum glucose is efficiently transported in tissues in situations where glucose concentration drops. While the carrier proteins located in beta cells (GLUT2) do show a high km ~20mM, as a higher km promotes for glucose sensing.
2. In order for muscle cells to raise sugar import INSULIN MUST BE PRESENT.
3. Oh, and glucokinase has a HIGH Km when compared to hexokinase.
Explanation: Glucokinase do possesses a minimal affinity (higher Km) for glucose as it will only function in situations of increased glucose concentration in serum.
4. Proton pumps are required for the release of transferrin from the transferrin receptor and iron form transferrin.
Explanation: H+ ATPases reduces the pH of the vesicle and results in transferrin to produce iron.
5. Iron Reductases Convert the iron to the active form in which it may be exported.
6. This happens in the Lysosome.
Explanation: Ferric iron is transformed into ferrous iron (which is the active type) through the activities of ferric reductase.
